Proton Pump Inhibitors (Includes Prevacid SoluTab) ↔ Bone Fractures

Moderate Potential Hazard, Moderate plausibility

Applies to: Osteoporosis

Various published observational studies have reported that PPI therapy may be associated with an increased risk for osteoporosis related fractures of the hip, wrist or spine. The risk was increased in patients who received high doses (multiple daily doses), and long term treatment (a year or longer). Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated. Caution should be used in patients at risk for osteoporosis related fractures and should be managed according to established treatment guidelines.


Proton Pump Inhibitors (Includes Prevacid SoluTab) ↔ Hypomagnesemia

Moderate Potential Hazard, Moderate plausibility

Applies to: Magnesium Imbalance

Symptomatic and asymptomatic hypomagnesemia has been reported rarely in patients treated with PPIs for at least 3 months, in most cases after a year of therapy. Serious adverse events can include tetany, seizures, and arrhythmias. Caution should be used in patients prone to magnesium imbalances such as patients taking other medications that can cause hypomagnesemia (e.g., diuretics). Regular monitoring is recommended.

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.
